Geometry problem help

1. In triangle ABC, if segment AB is perpendicular to segment BC, then segment AC is (always, sometimes, never) perpendicular to segment BC 2. As the number of sides of a regular polygon increases, the measure of each exterior angle (always, sometimes, never) decreases

AC is never perpendicular to BC. Since AB and BC are perpendicular, ABC is a right triangle with AC as its hypotenuse.

As the number of sides increase, the angles of regular polygons always increase. Triangle each angle is 60 degrees, square is 90, pentagon is 108, etc.

Dillon: 1. Triangle ABC as described is a right triangle with sides AB and BC with its legs and AC being the hypotenus of a right triangle. It can never be perpendicular to eithe of its legs. Answer: Never
2. Remember: Exterior angles are inversely proportional to interior angled . Exmple : Interion angle =
45 derees, exteriot = 180-45=135 degrees. Answer: Always

1. If the figure is a triangle and AB is Perp to _|_ BC then it is a rt triangle and ac is never _|_ to either of the other two sides.
2. As the number of sides of a regular polygon increase the exterior angles measures will decrease.
